My wife has a laptop computer. She has two big computing wishes - one is to have a big monitor for her laptop computer, and the second is to buy a 24" iMac. So I have been searching to find the cheapest solution to enable the IMac to work as a monitor. It seems ridiculous that the IMac doesn't have an input to be used as a monitor, but I guess Apple doesn't do everything right. But I would have expected to see a third party add-on to do the job. I'm not finding one in my web searches though. Any recommendations?
